The paper presents an active power filter control method. The reference signal is generated in the stationary reference frame α-β using multiresolution analysis and the controllers used are P-resonant controllers, suitable ...

Friction, especially its nonlinear components, may degrade the tracking performance of any servo drive systems. Focused on high precision positioning of DC electrical drive the paper proposes an easy method to compensate ...

The control of shunt active power filters using PWM inverters consists in generating a reference by separating, using different methods, the harmonics to be eliminated. The methods used are time-consuming and need dedicated ...

This paper presents an optimal control structure for variable speed, fixed pitch wind turbine. The control objective results from the optimization criterion that includes two contradictory demands: maximization of the ...

This work presents a modelling framework based on phenomena description of the process. The approach is taken to easy understand and construct process model in heterogeneous possible distributed modelling and simulation ...

This paper presents a method for calculating the reference currents needed for the command of an active filter. By using the Discrete Wavelet Transform (DWT) the high-frequency components of the currents are eliminated. ...

This paper analyses the performances of three different types of controllers for shunt active power filters. The controllers are used in the d-q frame, the same frame in which the reference signal for the 5th and 7th ...
